Abstract
A phase shifting circuit having a first delay element with a time constant .tau..sub.1, a second delay element with a time constant .tau..sub.2 smaller than .tau..sub.1 and a pulse generating element such as p-n-p-n transistor produces phase shifting pulses with respect to a reference phase upon application of a step-up voltage to the first delay element and periodic pulses to the second delay element. The two signals rise at different rate following respective curves and the two curves intersect at various points. The pulses generating element compares the two signals and produces a pulse at the instant the two signals coincides at the intersecting points. The phase shifting pulses have a linear phase relation with respect to the reference phase which is equal to the phase of the periodic pulses applied to the second delay element.
